Essays on Bacteria

In this review, we mainly focus on persistence colonization of Helicobacter pylori in the human gut. In recent times we have come across some novel strategies used by this bacterium can be a cause of prolonged existence in human or evolution with another bacterium to...

“ Bad breath is caused by odor-producing bacteria that grow in the mouth. When you don’t brush and floss regularly, bacteria accumulate on the bits of food left in your mouth and between your teeth. The sulfur compounds released by these bacteria make your breath...

Extremophiles are organisms that live in conditions which humans consider “extreme.” “Extreme” environments include but are not limited to extreme pressure, extreme cold, intense heat, highly acidic environments, and highly saline environments. These conditions were once believed to not have the ability to sustain life....

Vibrio cholerae is found mainly in raw vegetation, water containing sewage and raw seafood. Stagnant water and certain types of food, including seafood, raw fruits and vegetables, and grains are the most common sources of cholera infection. When a person consumes contaminated food or water,...

Viral Disease: Structure: Viral diseases are often associated as not living as they do not move and stay on the outside of a hosts cell. They are made up from strands of nucleic acids, these consist of either DNA or RNA, which are surrounded by...

Did you know, bacteria are a living and thriving species? “There are over ten million different types of bacteria! They can live within soil, in the ocean, or inside the human gut”. I am very interested in seeing what type of cleanser best kills these...

Bacteria are microscopic single celled organisms that thrive in diverse environments. They can live within soil, in the ocean and inside the human gut. The three basic bacterial shapes are spherical, bacillus and spiral. (Aryal.S,2015) Tuberculosis (TB) is a bacterial infection that spreads through inhaling...

What are archaeans? Archaea were discovered in the early 1970s. Same as bacteria they are single-celled. The unique structure of DNA of Archaea places it in the individual kingdom. There is still a lot of information we do not know about archaea. Most of them...

Poverty is one of the world’s recurring and concerning issues which has affected countries, especially third-world countries, and this includes Philippines. During the first half of 2014, 25.8% of the Philippine population suffers from poverty, which decreased to 21.6% in 2015, and was then increased...

Right through history, from the genus Mentha L. and the family (Lamiaceae), species which includes about 260 genera and more than 7000 species are being used worldwide and one example is Mentha piperita L. (Brahmi, Khodir, Mohamed & Pierre, 2017) commonly known as peppermint a...

Diagnosis of fowl cholera depends on identification of the causative bacterium, P. multocida, following isolation from birds with signs and lesions consistent with this disease. Presumptive diagnosis may be based on the observance of typical signs and lesions and/or on the microscopic demonstration of bacteria...

There are some bacteria in the environment that are so pervasive and detrimental as the disease process caused by them made it looks like we are getting eaten by an unseen entity typically known as the flesh-eating microbial agents. Among all of the sexually transmitted...

The discovery of antibiotics is one of the wonders innovations that humanity has experienced, but this light miracle died out just after the appearance of antibiotic resistance and the understanding of these origins and mechanisms. Although some authors have implemented corrective plans to minimize the...

Appearance of Antibiotic has greatly improved human health. Bacterial infections were once a leading cause of mortality in the societies, however, antibiotic invention decreased the mortality rate in bacterial infections considerably. Because of the antibiotics, the mortality rate decreased by 8.2% per year from 1900...

Introduction Ruminants diet is rich in fiber (consists of polymers e.g. cellulose) and low in proteins. Almost all animals as well as mammals lack the enzymes for metabolizing cellulose. Only microorganisms possess such enzymes which aid in fermenting cellulose and other polysaccharides consumed by the...

A microorganism is a living organism and they can only be seen through a microscope. Bacteria Bacteria cells are prokaryotic cells (single celled organisms). Bacteria cells have a variety of different organelles including a single circular strand of DNA, plasmids (small rings of DNA), a...

Introduction Bacteria is all around us despite that we are oblivious to its existence. It is common knowledge that bacteria exists, but it is easy for people to dismiss this fact as we cannot actually see the build-up of growth in surrounding areas. The colonies...

A facultative aerobe is an organism that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent. An obligate aerobe, by contrast, cannot make ATP in the absence of oxygen, and obligate...

In 2017, the World Health Organization compiled a list of “priority pathogens”, this list included 12 antibiotic-resistant bacteria. Acinetobacter baumannii made the slot for “priority one pathogen for antibiotic research and development. ” A. baumannii infects patients in critical care units, demonstrates multi-drug-resistance and can...

The blue green algae are the primitive members of the plant kingdom. The most of the blue-greens algae are unicellular, photoautotrophs and aerobic. They require mainly light, inorganic matter and oxygen for their growth. Spirulina are filamentous blue-green algae (cyanobacteria) always attracted the interest of...

I read the article “A stealthy superbug appears to be spreading in us hospitals, study finds.” And for the article on an additional case study, I read “With latest Zika research, our picture of the virus gets cloudier.” Just as mysterious as other viruses, scientists...

Yeast is one of the most important studies in the fermentation field. Yeast is eukaryotic fungi with different properties. It’s used in making many products such as milk, yogurt, bread and more. Yeast has most of the contents such as Golgi apparatus, nucleus, mitochondria, endoplasmic...

Salmonella spp The immune system is constructed to defeat any bacteria that can be a threat to body. However, salmonella knows when it enters the body of the host and it can change its behaviour to deal with our immune system and to cause infection...

Introduction Plant viruses are viruses that effect on plants. Plant viruses are obligate intracellular parasites. Plant viruses are pathogenic to higher plants. Viruses also cause many important plant diseases and are responsible for huge losses in crop production and quality in all parts of the...

By and large, for Gram-negative microscopic organisms, starved cells are morphologically and physiologically altogether different from log-stage cells. The underlying reaction to carbon-vitality source confinement is to attempt to dodge the stress by expanding expression or scavenging frameworks to have the option to use any...

Bacteria Biology Report Aim: To find the effects that disinfectants have on the kill zone at various concentrations on peppercorn bacteria in an incubated environment. Hypothesis: I believe that as we increase the concentrations of disinfectants the kill zone will increase in diameter. This is...

Antibiotic resistance crisis is happening now and it seems like there is no solution to it yet. Everyone knows that the antibiotic resistance is elevating to dangerously high levels in all parts of the world. The antibiotics that were used to save millions of lives...

The Paramecium tetraurelia is an unicellular ciliate that can be found in almost any sample of still water. Paramecium tetraurelia is a widely distributed, free-living unicellular organism that feeds on bacteria and can easily be cultured in the laboratory(Beisson,et al.,1970). Its large size and complex...

Acidithiobacillus strains SP5/1 and HV2/2 are rod-shaped, Gram-negative, γ-proteobacterium, aerobically pyrite-oxidizing and Acidophilic bacteria that thrives optimally at 30°C and 45°C respectively (Klingl, Moissl-Eichinger et al. 2011). S-layer molecular structure similarity in symmetry in the closely related species can be used as a taxonomic characteristic...

Introduction Recent studies have allowed us to come to the conclusion that we are super organisms in which microbial symbionts play essential physiological functions. The human microbiome has emerged as the crucial moderator in interactions between food and our body and can change our mind...
